- - 737-800 descent angle in different configurations (https://www.pprune.org/tech-log/509106-737-800-descent-angle-different-configurations.html)

He quoted "F20 idle thrust in a 757 gives 6 deg descent path" and wanted to know how the 738 compared......

So if you're on a visual approach hand flying the beast around the circuit you may not want to be banking 30 deg while "dive bombing" down F20 idle thrust to recover a stuffed up approach..... Call me an old fart but that is a recipe for disaster!!

I guess if you were conducting a straight in Vis approach and ATC ( or terrain ) left you high then this info would be useful to recover back to profile. For a new Pilot on a type I'd suggest this isn't an ideal situation to be in until you do get to know the Aircraft.

I can see what he's after but I'd suggest he get used to the 738 in normal ops first.

Anyway....

It sounds like he understands jets, and just needs a piece of unpublished info. "I can do X in plane A, can I do X in plane B?" Yes. Problem solved.

I do not understand the following,is it for level flight or descend?
Speed Vref + 5kts, F15 : BA 5° and thrust at 52%
Speed 140 kts, F25 : BA 4° and thrust at 52%
